It is the primary object of the invention to The metering chamber 9 is provided with la provide a novel and improved meter structure cup-like extension at .25 into which the shaft capable of handling grease and other heavy lubrielement I6 projects. The screw 26 adjustably -5- cants and provided with an adjustable and yieldthreaded into the bottom of the cup 25 carries a able bearing for the shaft of the wobble disk; headed pin 21 which serves as an axis upon with means for Icy-passing sufficient lubricant to which the tapered frusto-conical roller 28 is lubricate the wobble disk bearings without materotated. The roller is yieldably supported at a 10 rially affecting the meter reading; with a comgiven elevation on pin 2l Aby means of a resilient l0 bined register gear train and change speed gear compression washer 29 comprising a convoluted set; and with a novel and improved register conannular spring acting through a thrust washer UNITED ST struction. 30.

The space I4 below this practice to have a set of change gears and a partition represents the high pressure side of the separate register gear train. In the present demeter to which the lubricant to be metered is vice the register gear train and the change gear admitted through port I8. The lubricant which set is consolidated in one unit, this being possible 50 passes through the metering chamber and escapes primarily because of the fact that the lubricant from port II enters the low pressure chamber I9 handled by the meter has access to the entire of the meter casing and will substantially fill gear train and thereby protects it from the overchamber I9, whereby to lubricate all of the gearload which would occur if it were less well lubriing hereinafter to be described. Thence the cated.

'Ihe orbital movement of the shaft I1 is transmitted to an arm 35 mounted on the driving shaft 36 of the gear train. Thence motion is transmitted to pinion 31, gear 38, pinion 39, and gear 40, to the intermediate shaft 4I which is provided removably with the interchangeable change speed gear 42.

The change speed gear 42 meshes with a second change speed gear 43 removably fixed to the lower end of shaft 44, which carries pinion 45. This pinion drives the totalizer gears 46 and 41. Gear 46 is connected with a worm 48 which drives a worm wheel 49 on the totalizer shaft 50. This shaft operates the rst of a series of totalizer disks 5I, 52, and 53, bearing numerals on their peripheries which are exposed through a window slot at 54 to show the total number of units metered.

The gear 41 is mounted on a shaft 55 which projects upwardly through the top of the meter casing and drives an indicator which may be reset to zero after the commencement of each metering operation.

Screwed to the top of shaft 55 is a disk 56 recessed to receive one or more spring biased clutch elements 51. In the direction of rotation of shaft 55 these clutch elements engage the cylindrical inner periphery of the cap-shaped handle member 58 to rotate such member in the direction to advance its indicating pointer 59 over a calibrated scale carried by the top of the meter casing. The handle member 58 would be freely removable axially from shaft 55 if it were not connected by set screw 6B with an interior thimble 6I apertured to receive the shaft 55 and anchored beneath the disk 56. Thus the thimble 6l and the handle 58 turn unitarily together, the handle constituting an enclosure for the disk 56 and the clutch mechanism, and the thimble providing means for securing the handle against removal. The clutch mechanism permits the handle to turn freely with respect to the disk 56 and shaft 55 toward the zero point on the calibrated scale.

I claim:

1. In a meter` of the class described, th-e combination with a casing comprising upper and lower sections, of a metering chamber within said casing arranged to discharge the material metered into the upper section thereof, a motor element within said chamber having an orbitally movable pin in said upper casing section, a gear train support intermediate the height of said upper section, a gear train comprising a driving shaft operatively connected to receive motion from said pin, a set of motion reducing gearing above said support comprising shafts projecting downwardly through said support, and intermeshing gears removably mounted below said support on said shafts, a driven shaft operatively connected to receive motion from said train, and a total-indicating register operatively arranged to be actuated by said driven shaft.

2. In a meter of the character described, the combination with a meter casing comprising suitably apertured inlet and outlet sections, of a metering chamber confined between said sections and having inlet and outlet ports communicating with the respective sections, said chamber constituting a partition between said sections, a wobble disk piston within said chamber provided with a spherical bearing element, said chamber having concave seats centrally apertured to receive said element, a pin projecting from said element through the aperture of one of said seats toward the inlet section of said casing, a chamber extension enclosing said pin and provided with a by-pass duct to admit thereto a minute portion of the material entering said inlet section, a gear train disposed in the outlet section of said casing and operatively connected with said piston to receive motion therefrom while fully exposed to the eflluent from said chamber, and a totalizing register mounted on said casing and operatively connected with said train to be actuated thereby, together with a tapered bear* ing disposed in said chamber extension and deiining the orbital path of movement of said pin, said bearing comprising an adjustable mounting and a yieldable support for said bearing on said mounting.
